You don't need to worry or treat me differently. I just wanted you to know, because it helps when the people close to me understand why some days are harder than others.

I'm still getting my head around all of this myself. I just didn't want to keep it from you.

Thank you for asking; it honestly means a lot.

The most helpful thing isn't doing anything specific. It's just believing me when I say I'm tired or can't make it, without needing an explanation every time. Some days I'll be fine and then crash the next day. That's not me being flaky; it's the disease.

If we're making plans, it helps to keep them flexible. Low-key options are usually better than big events, and knowing I can leave early without guilt makes a real difference.

And if I ever seem withdrawn or quiet, please don't take it personally. Managing a chronic illness is exhausting in ways that are hard to put into words. Your friendship matters enormously; I just sometimes don't have the energy to show it the way I'd like to.
